Selecting objects with the same property values (without Python)
I don't think there is a way to do this without some Python. It is not very complicated though. 

You can type C.object. and hit Ctrl+Space in the Python Console to see all the properties. Also they might be in C.object.data.. Once you know the property you wish to select your objects based on, you can run:

import bpy

for obj in bpy.context.scene.objects:
    # Note that floats may not be equal because of binary rounding errors so:
    if (obj.location[2] - 1.0694) &lt; 0.0001 and (obj.location[2] - 1.0694) &gt;= 0 : 
        obj.select = True
        bpy.context.scene.objects.active = obj #to make the last selected object active
    else:
        obj.select = False


Obviously you would change (obj.location[2] - 1.0694) &lt; 0.0001 and (obj.location[2] - 1.0694) &gt;= 0 to whatever statement comparing properties to your wanted values.
